through function pointers).</td> +</tr> +<tr> +<td><b>core.AttributeNonNull</b></td><td>Check for null pointers passed as arguments to a function whose arguments are marked with the 'nonnull' attribute.</td> +</tr> +<tr> +<td><b>core.CallAndMessage</b></td><td>Check for logical errors for function calls and Objective-C message expressions (e.g., uninitialized arguments, null function pointers).</td> +</tr> +<tr> +<td><b>core.DivideZero</b></td><td>Check for division by zero.</td> +</tr> +<tr> +<td><b>core.NullDereference</b></td><td>Check for dereferences of null pointers.</td>

for undefined results of binary operators.</td> +</tr> +<tr> +<td><b>core.VLASize</b></td><td>Check for declarations of VLA of undefined or zero size.</td> +</tr> +<tr>
